The Nature Conservancy

The Nature Conservancy is the leading conservation organization working around the world to protect ecologically important lands and waters for nature and people. We address the most pressing conservation threats at the largest scale. Thanks to the support of our more than 1 million members, we’ve built a tremendous record of success since our founding in 1951: We've protected more than 119 million acres of land and thousands of miles of rivers worldwide — and we operate more than 100 marine conservation projects globally. We work in all 50 states and more than 35 countries — protecting habitats from grasslands to coral reefs, from Australia to Alaska to Zambia. See where we work. We address threats to conservation involving climate change, fresh water, oceans, and conservation lands.
